FIG. 2

INVENTOR. JAY GOULD LIVINGSTONE ATTORNEY Patented Sept. 28, 1954 UNITEDSTATES FFECE GAPPED VESSEL WITH ADAPTER Jay Gould Livingstone, Akron,Ohio 3 Claims.

This invention relates to a pouring adapter or attachment of resilientplastic, for a glass bottle, metal can or other vessels for liquids. Theadapter is held in the neck of the vessel by friction or otherwise. Itis provided with a flange which fits over the end of the neck of thevessel and serves as a sealing gasket. A ca fits over the adapter and isfastened to the outside of the vessel by being threaded on the neck orby other means. For instance, it may be snapped in place. The cap isprovided with a surface which presses the flange of the adapter againstthe end of the neck of the vessel (either the outside rim or the insiderim or intermediate the two or elsewhere) so that it serves as a sealinggasket, one surface of the flange being brought into liquidtight contactwith the cap and the other surface of the flange being brought intoliquid-tight contact with the end of the neck of the vessel. The cap mayor may not include a liner. As a rule, additional gasketing meansbetween the flange and the end of the vessel is superfluous. Thus thevessel is sealed so that there is no leakage of liquid either above orbelow the flange.

The invention will be more particularly described with reference to arun-back type of adapter, but any other pouring adapter may be employedwhich is designed so that all liquid which enters the opening in theadapter and is not poured from the adapter is returned to the vesselwhen the vessel is brought to the upright position. For instance, theadapter may be so designed that liquid poured through it is dischargedby pouring it over the flange. In this case the vessel will generally besealed with the conventional non-dome-type closure cap. The function ofthe runback type of adapter is explained in detail in my Patent No. 2,601,039; the present application being a division of my applicationSerial No. 290,227 which is a division of that patent. The adapter isheld to the neck of the vessel, even though the cap be removed and thevessel be inverted. There is an opening through the adapter throughwhich the liquid contents of the vessel may be poured.

Figure l is a section through a capped bottle using one type of pouringadapter, and

Figure 2 is a section through a different type of pouring adapter in abottle.

The pouring adapter of both figures of the drawing includes a pouringspout A surrounded by a channel B which slopes from the portion underthe pouring spout to the rear of the adapter. The adapter is fitted inthe neck of a glass bottle C. The rear of the spout is open as shown inthe drawings and liquid which collects in the channel is returned to thebottle through this opening. Any liquid dripping or draining from thespout A collects in the channel and thus is returned to the bottle. Itis for this reason that such adapters are called run-back adapters.

In Fig. l, the adapter I is friotionally fitted into the neck of bottleC by the annular flange 2. This flange is an integral part of theadapter. Any flange formed integrally with the outside of the adapter,which flange engages with the inside surface of the bottles neck may beemployed. A closure cap 4 having an offset portion 5 is used to closethe bottle. The cap is screwed to the neck of the bottle and when it isremoved the adapter will be retained in the bottle by the flange 2 orits equivalent.

The flange 6 is formed integrally with the adapter, being an extensionof the outer wall of the channel B. It projects over the end of the neckof the bottle. The horizontally projecting portion I of the cap pressesthe flange tightly to the bottle when the cap is screwed tight on to thebottle.

The adapter of Fig. 2 is provided with a flange ls extending outwardlyfrom the upper edge of wall H which bounds the channel B. A flexibleskirt [3 extends downwardly from the bottom edge of wall I i and itsbottom portion flares outwardly. The skirt is fltted into the neck 15 ofthe bottle by collapsing the sides of the flexible skirt and pressingthe outwardly flaring bottom it through the neck of the bottle. When thespout is in the bottle, flange l0 rests on the rim of the neck and theflaring bottom embraces the base of the neck inside the bottle so thatthe spout is held tightly in place. A dome-shaped cap as shown in Fig. 1may be threaded onto the threads l8 with the flange [0 serving as asealing gasket.

The bottom of the flexible skirt 13 may be tapered inwardly to form alead section to facilitate introduction of the adapter into the vessel.

The adapter may be molded from any resilient plastic, e. g.polyethylene. Such a spout works equally well with milk, water, wine,whiskey, oils, and sirups, etc.

What I claim is:

1. In combination with a Vessel having a neck and an opening at the endthereof, liquid in the vessel, a cap which encloses the opening and isfastened externally tothe vessel, and under the cap a pouring adapter ofresilient plastic having an opening therethrough which adapter isengaged with the neck, the adapter having a flange integral therewithwhich extends radially outwardly between the cap and the end of the neckand is squeezed therebetween so that the flange is in sealing contactwith both the cap and the end of the neck so that no liquid escapes fromthe capped vessel when it is upset, the surface of the adapter from thecap to the opening through the adapter draining to said opening, wherebywhen the cap is fastened to the vessel and the vessel is upset liquidwhich flows from. the vessel through the opening in the adapter isreturned to the vessel when the vessel is brought to the uprightposition.

2. In combination with a vessel having a neck and an opening at the endthereof, liquid in the vessel, threads on the outside of the neck, arigid cap which encloses the opening and is threaded on said threads onthe outside of the neck, and under the cap a pouring adapter ofresilient plastic having an opening therethrough tact with both the capand the end of the neck,

so that no liquid escapes from the capped vessel when it is upset, thesurface of the adapter from the cap to. the opening through the adapterdraining to said opening, whereby when the cap is fastened to the vesseland the vessel is upset liquid which flows from the vessel through theopening in the adapter is returned to the vessel when the vessel isbrought to the upright posi-,

tion.

3. In combination with a vessel having a neck and an opening at the endthereof, liquid in the vessel, a cap which encloses the opening and isfastened externally to the vessel, and under the cap a pouring adapterofipolyethylenehaving an opening therethroughwhich adapter is engaged inthe neck, the adapter having a flange integral therewith which extendsradially outwardly between the cap and the end of the neck and issqueezed therebetween so that the flange is in sealing contact with boththe cap and the end of the neck, so that no liquid escapes from thecapped vesselwhen it is upset, the surface of the adapter from the capto the opening through the adapter-draining to said opening, wherebywhen the cap is fastened to the vessel and the vessel is upset liquidwhich flows from the vessel through the opening in the adapter isreturned to the vessel when theivessel is brought to the uprightposition.
